A rainy day indicates any day with measurable rainfall and does not mean it rains continuously for the entire day.
Average Daily Sunshine Hours
The average daily sunshine is calculated by taking the month’s total recorded sunshine hours and dividing that figure by the number of days in the month. Sunshine duration is measured using specialised instruments such as a Campbell-Stokes recorder.
Average Sea Temperature
Average sea temperature for a month is calculated by taking the daily sea-surface readings and averaging them across all days in that month. These measurements come from a range of sources, including ocean buoys, ships, and satellite sensors that estimate temperature from the energy emitted by the water's surface.
